10 most important differences between OpenShift and Kubernetes

Containerization deals with this problem through bundling of the application code with configuration files, dependencies, and libraries for running it. Kubernetes (sometimes referred to as K8s) is a popular open source platform that orchestrates container runtime systems across a cluster of networked resources. To access the Kubernetes Web GUI, you will need to install the Kubernetes dashboard and forward your local machine’s port address to the cluster server using kube-proxy. Since the dashboard lacks a login page, you will also have to create bearer tokens that facilitate authorization and authentication.

  1. Now that you have a sense of how cluster container orchestration works, you can better understand Kubernetes’ features and what Kubernetes offers for your business.
  2. These container images can then be deployed and run on any platform that supports containers, such as Kubernetes, Docker Swarm, Mesos, or HashiCorp Nomad.
  3. Here, Kubernetes can be deployed as a platform-providing service, with many vendors providing their own branded distributions of Kubernetes.

OpenShift has more strict security policies than default Kubernetes

Kubernetes deployment objects can handle multiple and concurrent updates. Web-based User Interface (UI) is important foreffective cluster administration. You have to install the Kubernetes dashboardseparately and use the kube-proxy to forward a port of your local machine tothe cluster’s admin server. In addition, you have to manually create a bearertoken to provide authorization and authentication, since the dashboard does nothave a login page.

Properly configured requests and limits enable Kubernetes to make informed scheduling decisions, placing containers on the most appropriate nodes and maintaining cluster efficiency. Namespaces provide a mechanism for isolating groups of resources within a single Kubernetes cluster. They can be seen as a layer of abstraction added to the cluster to allow multiple teams or projects to share the cluster without overlapping.

Why Red Hat?

In this article, I’m describing real differences between OpenShift and Kubernetes. It’s often confusing, as Red Hat tends to describe it as PaaS, sometimes hiding the fact that Kubernetes is an integral part of OpenShift with more features built around it. Red Hat OpenShift 4 is the next generation of trusted enterprise Kubernetes platform.

Kubernetes supports multiple deployment strategies out of the box, can manage your network ingress, and provides observability out of the box into your containers. All major cloud vendors offer managed Kubernetes services that make it significantly docker vs kubernetes vs openshift easier to get started and take advantage of cloud native features, like auto-scaling. While Kubernetes provides the foundation for container orchestration, OpenShift builds upon this foundation to offer a comprehensive container solution.

For deploymentconfig and many controllers — such as replication and namespace controllers — Kubernetes might be considered a more comprehensive option. On the whole, both Kubernetes and OpenShift provide a high-functioning continuous integration and continuous delivery (CI/CD) process. Though you’ll find certain CD pipeline features may better support your business needs.

Still, there are few hindrances CXOs or technology managers are facing regarding container solutions in terms of management, scaling, agile deployment and sustenance. You need to integrate both Platforms with additional tools likeautomated testing and monitoring, and CI servers to build a full CI/CDpipeline. Docker is well known and has long been the standard tool for containerization. To make this self-contained application, a Dockerfile is first created, which specifies a base image, dependencies and the necessary steps to set up, build and run the application. This Dockerfile is simply a text file used to write the steps to build the Docker container.

In contrast, OpenShift has robust security features for safeguarding containers, including an integrated authentication and authorization server. With Docker, you can use a simple API to execute commands and automate tasks. While Kubernetes uses kubectl, a powerful API and command-line tool, to automate most container management tasks. The platform stores data about objects within etcd, a reliable clustered key-value store.

Kubernetes also automates the process of scaling applications up or down based on demand, helping to manage resource consumption efficiently. This automation extends to self-healing capabilities, where Kubernetes can detect and replace non-responsive or failing containers, ensuring high availability and reliability of applications. Kubernetes automates various aspects of the application lifecycle, from deployment and scaling to updating and maintenance.

OpenShift follows the same pattern, packaging Kubernetes with bug fixes, security patches, CI/CD tools and other development tools. Commercial support is also offered for troubleshooting and resolving any issues that come up. There are several advantages of using Docker over more traditional options, such as VMs. Also, the Dockerfile serves https://forexhero.info/ as documentation for the application’s runtime environment. The choice between OpenShift, vs Kubernetes vs Docker, will depend on an organization’s specific needs and requirements. By understanding the strengths and weaknesses of each container platform, organizations can make informed decisions that enable them to achieve their goals.
